Intelsat 35e, also known as IS-35e is an Intelsat high-throughput (HTS) geostationary communications satellite designed and manufactured by Boeing Satellite Systems on the Boeing-702MP satellite bus.[4][5] It was launched on 5 July 2017.[2]
It is the fourth satellite of the EpicNG service and covers the Americas, Europe and Sub-Saharan Africa from the 34.5° West longitude.[6] It has a mixed C-band and Ku-band, with the C-band featuring EpicNG spot beams.[4][5][7]
Satellite description
Intelsat 35e was designed and manufactured by Boeing Satellite Systems on the Boeing 702MP satellite bus. It had a launch mass of 6,761 kg (14,905 lb), the largest Intelsat's currently active satellite,[8] and has a design life of more than 15 years.[4][5]
It is powered by two wings, with four
Its payload was the fourth high-throughput EpicNG deployment. The EpicNG is characterized by the implementation of frequency reuse due to a mix of frequency and polarization in small-spot beams. Not only applied to the classical HTS Ka-band, but also applying the same technique in Ku-band and C-band. The EpicNG series also keep the use of wide beams to offer high throughput and broadcast capabilities in the same satellite.[6]
In the case of Intelsat 35e, the C-band side has EpicNG spot beams with a total downlink bandwidth of 4,356 MHz. The spot beams offer high bandwidth for Europe, Sub-Sahara Africa, and the Americas. The Ku-band has 39
History
In July 2009, Intelsat became the first customer of the Boeing 702MP satellite bus, when it placed an order for four spacecraft to be built, Intelsat 21, Intelsat 22, Intelsat 27 and the first EpicNG satellite, Intelsat 29e. In May 2013, Intelsat contracted for an additional four EpicNG satellites, the first of which would be Intelsat 33e.[9] On 8 July 2014, Boeing announced a ninth 702MP order, and sixth EpicNG,[inconsistent] for the Intelsat 35e.[10] During 2014, Intelsat announced to service contract where the clients would start using Intelsat 903 at the 34.5° West position and then seamlessly transfer their services to Intelsat 35e as soon as it was commissioned into service.[11][12]
Launch history
Following two aborted launch attempts earlier in July 2017, Intelsat 35e was launched on 5 July 2017 from the
During an interview with Intelsat's CEO Stephen Spengler in February 2016, it was disclosed that Intelsat 35e was expected to launch in 2017.
Intelsat 35e was initially prepared for launch on 2 July 2017 from launch pad 39A, with a 59-minute-duration
Intelsat 35e was successfully launched and placed in orbit on 5 July 2017.[2]
